Elvis Nickel Alloys, located in Houston, USA, stands out as a top-notch manufacturer and supplier of Super Duplex Steel Threaded Rods. These rods are celebrated for their remarkable strength and outstanding resistance to corrosion, especially in tough environments. Crafted from high-performance materials like UNS S32750 and UNS S32760, they’re perfect for situations where exposure to chlorides, high mechanical stress, and chemical attacks are a concern. Thanks to their balanced austenitic-ferritic microstructure, Super Duplex threaded rods boast double the strength of regular stainless steel and are resistant to pitting, crevice corrosion, and stress corrosion cracking. You can get them in standard or custom lengths, and they meet standards like ASTM A193 and DIN 976.
Super Duplex Steel Threaded Rods are made up of about 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with trace amounts of copper, manganese, and silicon. This unique blend gives them impressive tensile strength (up to 800 MPa), yield strength of at least 550 MPa, and excellent impact toughness, even in cryogenic conditions. The alloy’s high PREN (Pitting Resistance Equivalent Number) guarantees exceptional resistance to corrosion caused by chlorides. These rods maintain their shape under stress and are perfect for both static and dynamic loads in harsh settings.
